Does my MAF Look ok? (logs inside)

[Beaker™]

Just got Vagcom working so had a go at logging the airflow as my MAF is playing up. This log shows it peaking at 150g/s which ok yeah?

looks ok for the short run you've done - only logs to 4800

I know, my car really tails off after that so i figured the airflow would be lower after that. Plus the traffic is busy.

Would logging blocks 014 and 015 log anything if i had a missfire while logging?

 

[Beaker™]

I did get to 4680rpm earlier but for some reason the overall airflow was lower then.

You'll get a higher reading the further up the rev range you go. You running a ko3? If yes then around 150g/s is fine.

 

[m0rk]

best I've logged on K03 was 158, but as you say - it was at higher revs

 

[-pseudonymous-]

Yeh M0rk i only ever saw mid 150's max on the ko3, but seeing mid 180's now on the ko3's.

Block 014 and 015 will show a count yeah on whatever cylinder you have a misfire, but i think you can only log them at idle. I could be wrong though.

 

[Big_daddy]

I got 168g out mines.

Thats pretty high for a ko3 but not unheard of. Your seeing slightly excessive timing pull on that log though.

 

[Big_daddy]

Its a Ko3s on a app block (as i can only see one vacum line on actuator).
what timing should i be seing (do no much about how timming works).

 

[-pseudonymous-]

Ideally you want to be seeing 3's but the odd 4 or 5 max is acceptable occasionally. What re-map do you have? Have you got a FMIC fitted?

 

[Big_daddy]

Its performance torque remap, sorry standard IC.
Here is the link of my previous logs

Sorry is this a leon or an ibiza? I would advise getting a fmic fitted because your seeing a fair bit of timing pull there. What were the ambient temperatures like at the time you did the logs because they were done in august unless i'm mistaken? Have you done any more recent logs in the cooler weather?

Yes its a leon, Yeh fmic is next on my list, didnt measure that only done intake temp.what block is that? The felt abit slow then, but now feelers quicker. do some logs over the weekend.

You don't measure ambient through vag-com, it should be displayed on you dash somewhere. A fmic is a worthwhile mod in my opinion, i would definitely splash out on one before the warmer weather comes. Your car will perform all year round then.

Oh that I think it was around 16-20degress, yeh saving my pennies for that follwed by suspension and new braking (Big credit bill coming my way)
